在简单类上使用NullReferenceException导致Xml序列化失败

我已经得到了要序列化的简单类:

public class InnerCharacter : Object {
    public double xp;
    public double hp;
}

我尝试不同的方法，例如:

public static void TestSerialize()
{
    InnerCharacter c = new InnerCharacter();
    Serialize(c);
}
static public void Serialize(InnerCharacter details)
{
    XmlSerializer serializer = new XmlSerializer(typeof(InnerCharacter));
    using (TextWriter writer = new StreamWriter(@"Xml.xml")) {
        serializer.Serialize(writer, details);
    }
}

我也尝试了文件流和其他方法，但它们都导致相同的异常。以下是我如何尝试在Unity中加载代码，在我的一个GameObjects上:

public void Start()
{
    TestSerialize();
}

它们都以相同的NullReferenceException失败:

NullReferenceException

在简单类上使用NullReferenceException导致Xml序列化失败

XmlSerializer不能处理继承自UnityEngine.Object的对象。来源:XML序列化错误。
